That all being said, I'd like to make a motion that should simplify
everyone's life - if only for a bit. I'm thinking of making all
containers classes (either final classes or at a minimum classes with
only final methods). Currently containers are implemented as structs
that are engineered to have reference semantics. Some collections use
reference counting to keep track of the memory used.
Thinking about this I've found an interesting issue:
---
void foo(int[int] aa)
{
aa[2]=2;
}
int main()
{
int[int] aa;
//aa[1]=1; //uncomment this and it will work
foo(aa);
assert(aa[2]==2);
return 0;
}

Yah, this has been discussed many times. Essentially AAs have class-like
semantics with null in tow.
